Luminescent properties contrast between nanocrystal and microcrystal of Ca_4Y_6(SiO_4)_6O∶Eu

In this paper, the naonocrystalline and microcrystalline Ca_4Y_6(SiO_4)_6O∶Eu were synthesized by controlling the sintering temperature and hours. Some questions about Ca_4Y_6(SiO_4)_6O∶Eu nanocrystal were studied, which include: luminescent properties, the relationship between luminescent intensity and temperature. At the same time, the influence of the sintering temperature and the synthesizing method to the quenching concentration of Eu~(3+) in Ca_4Y_6(SiO_4)_6O∶Eu were discussd too.
